Hello everyone,anybody knows if the easycompoaites very high temp epoxy can partial post cured at 60-70c?what will be the Tg?

As said a good rule of thumb is the resin will have a TG around the temperature you postcured it to, especially in the early stages since initial cure.

You will find with time, the TG will improve as some of the uncured resin naturally cures, however you are not going to achieve the full 180C Tg naturally no matter how long you leave it as there isn't enough energy at room temperature to achieve the full level of cure needed.

Hence we always recommend a full postcure to achieve the highest possible Tg and best mechanical properties.
